A mirror always
Answer: A
A mirror always reflects.
A mirror is a smooth, highly polished surface whose essential property is to reflect light, so that images are formed. Every mirror, plane, concave or convex, works by reflection.
Refraction, the bending of light as it passes from one medium into another, is how lenses work. Distortion happens only with curved or uneven mirrors, not always, and 'retracts' has nothing to do with light.
